沙门菌SopB蛋白在侵袭宿主细胞中的作用机制

【摘要】:沙门菌是一种革兰阴性肠道病原菌,其通过"触发"机制,依赖沙门菌致病岛(Salmonella pathogenicity island,SPI)编码的Ⅲ型分泌系统(typeⅢsecretion system,T3SS)将效应蛋白转运至宿主细胞,调节宿主细胞功能。SopB是SPI-1编码的效应分子之一,其在沙门菌侵袭宿主细胞过程中发挥多重生物学功能,如介导细胞骨架重排,促使Akt发生磷酸化修饰进而抑制细胞凋亡,激活一氧化氮合酶(iNOS),并能诱导沙门菌包含小泡(Salmonella containing vacuole,SCV)的初步形成及成熟,为沙门菌在宿主细胞内的存活及增殖提供了一个微环境。
